MW> And what should getmaxcolor return for 160x200x4 on C64: 4 or 16? you say it yourself... if you call the mode 160x200x4, the maximum of colors _IS_ 4, so the function should return 4 ;=) the function that sets the color-palette should give you "4 out of 16 possible colors" so you can set those accordingly. -- Best regards, groepaz mailto:groepaz_at_gmx.net ---------------------------------------------------------------------- To unsubscribe from the list send mail to majordomo_at_musoftware.de with the string "unsubscribe cc65" in the body(!) of the mail.
